Abstract

TAMARINDUS INDICA SEED: HERBAL ALTERNATIVE TO SYNTHETIC ACID- BASE INDICATOR

Professor Monika Bhalchandra Savalkar*, Shital Suhas Gaikwad*, Yasmin S Mulani, Tejas Ganesh Kale

ABSTRACT

Today synthetic indicator is the choice of acid base titrations. But due to environmental pollution availability and cost the search of natural compound as an acid base indicator was started. Indicator is very special chemicals they changes colour of solution with changes in pH by adding acid or alkali. In the present work acid base titration has been performed by using natural indicator aqueous & methanolic extract of seed were used as natural indicator. Two acid (HCL and CH3COOH) and two base (NaOH and KOH) were selected for titration .0.1N acid and base were prepared. The result obtained by the natural indicator almost similar to synthetic indicator. Thus natural indicator from seed can be used for acid base titration at any dilution. Using aqueous extract from of seed as indicator is more economical and with the same accuracy of result as the given by synthetic indicator.
